The BPC157, TB500 (43 amino acid Thymosin Beta-4), KPV, and GHK-Cu quad blend combines four well-studied peptides that work through different but complementary pathways. BPC157 has been researched for supporting faster tissue healing, new blood vessel growth, and protection of the stomach and gut lining. TB500, the full 43aa Thymosin Beta-4 peptide, helps regulate actin, a key protein for cell movement and repair, and plays an important role in wound healing and tissue regeneration. KPV, a short fragment of alpha-MSH, is known for its anti-inflammatory and antimicrobial effects, mainly by reducing overactive immune signaling. GHK-Cu is a natural copper-binding peptide that stimulates collagen production, skin and hair regeneration, and cellular repair. Together, these four peptides may act synergistically—BPC157 and Thymosin Beta-4 strengthen repair and blood flow, KPV calms inflammation, and GHK-Cu drives tissue remodeling and renewal—making this blend a broad research platform for studying healing and regeneration.
